Get started with TTLock Devices

Learn how to connect and control your TTLock locks with the Seam API.


Seam provides a universal API to connect and control many brands of locks, including TTLock. This guide provides a rapid introduction to connecting and controlling your TTLock locks using the Seam API. To learn more about other device brands supported by the Seam API, such as August, Igloohome, Schlage, and Kwikset, head over to our integration page.

1 — Install Seam SDK

Seam provides client libraries for many languages, such as JavaScript, Python, Ruby, PHP, and others, as well as a Postman collection and OpenAPI spec.

npm i seam

Once installed, sign-up for Seam to get your API key, and export it as an environment variable:

$ export SEAM_API_KEY=seam_test2ZTo_0mEYQW2TvNDCxG5Atpj85Ffw

This guide uses a Sandbox Workspace. Only virtual devices can be connected. If you need to connect a real TTLock device, use a non-sandbox workspace and API key.

To control your TTLock locks via the Seam API, you must first authorize your Seam workspace against your TTLock account. To do so, Seam provides Connect Webviews: pre-built UX flows that walk you through authorizing your application to control your TTLock devices.

Request a Connect Webview

from seam import Seam

seam = Seam()

webview = seam.connect_webviews.create(accepted_providers=["ttlock"])

assert webview.login_successful is False

# Send the webview URL to your user

Authorize Your Workspace

Navigate to the URL returned by the Webview object. Since you are using a sandbox workspace, complete the login flow by entering the TTLock sandbox test accounts credentials below:

  • email:

  • password: 1234

Confirm the Connect Webview was successful by querying its status:

updated_webview = seam.connect_webviews.get(webview.connect_webview_id)

assert updated_webview.login_successful # true

3 — Retrieve TTLock Devices

After a TTLock account is linked with Seam, you can retrieve devices for this TTLock account. The Seam API exposes device properties like battery level, lock status, and more.

all_locks = seam.locks.list()

some_lock = all_locks[0]

assert["online"] is True
assert["battery_level"] is True

# Device(device_id='60d0f1b6-26ae-4366-8d1b-d20ad0d6a62e', device_type='ttlock_lock', location=None, properties={'locked': False, 'online': True, 'manufacturer': 'ttlock', 'battery_level': 0.86, 'ttlock_metadata': {'lock_id': 545636388, 'lock_alias': 'Office Lock'}, 'supported_code_lengths': [4, 6, 8], 'name': 'Office Lock'}, capabilities_supported=['access_code', 'lock'], errors=[])

4 — Locking & Unlocking a Door

The Remote Unlock feature must be enabled in your lock settings in order to unlock a TTLock device. To do so, open the TTLock app, navigate to your lock settings, and turn on the Remote Unlock feature.

If we detect that this feature is disabled, a warning is added to the device.

Next, you can perform the basic action of locking and unlocking a door.

Unlock a door


Request Body




# lock the door
updated_lock = seam.locks.get(some_lock.device_id)
assert["locked"] is True

# Now unlock the door
updated_lock = seam.locks.get(some_lock.device_id)
assert["locked"] is False

5 — Setting Access Codes on TTLock Devices

The Seam API makes it easy to program both ongoing codes and timebound codes on a TTLock device. You can find out more about access codes in our core concept section on access codes.

# create an ongoing code
  name="Personal Access Code")

# create a timebound code
  name="My Temp Access Code",

# you can use a device or a device_id as the "device" parameter

Next Steps

Now that you've completed this guide, you can try to connect a real TTLock device. To do so, make sure to switch to a non-sandbox workspace and API key as real devices cannot be connected to sandbox workspaces.
